KRUPP AKTIEN GESELL- SCHAFT, 0F ESSEN-ON-THE-RUHR, `GERMANY' Application filed February 26, 1929, Serial .No.i 342,882, and in Germany April 13, 1928.

The invention relates to mechanisms for ure land shows the tens key board,

adjusting the lines on vouchers to be vintroduced in the printing mechanism of a bookkeeping machine or the like, '1n which mechanisms the table intended to receive the voucher is so moved i-n dependence upon a special setting mechanism that the line to be printed of the Voucher is brought to coincidence with the printing line of the printing mechanism.

4Vith'known mechanisms of this type the table is moved by an external force acting upon it onto stops that are set by the setting mechanism, the number of these stops or, if a single adjustable stop is made use of, the number of its stop positions corresponding to the number of the lines of the voucher, so

l than-if the voucher'comprises e. g. 39 lines,

39zkeys are required. .l

According to the invention, the lsetting mechanism is subdivided decimally, so that the units, tens, hundreds etc. of the consecutive number of the lines of the voucher may be set separately.

Furthermore.,l according to the invention the table is moved onto the stop set not by an external force with the concurrence of springs, but by a differential mechanism of the tongs-closure type.

By these means therefore both the setting l mechanism is simplified, because e. g. for .39

' lines only 1-2keys are required, and the motion ofthe voucher table onto the stop takes place with absolute security, even if a great resistance obstructs the' motion of the table,

e. g. by the introduced voucher crimping.

In order to allow of the invention to be more easily understood, a preferred embodif ment of the subject-matter of same is illus trated by wayof example in the accompany- Ving drawings as applied .to a book-keeping machine having'a squarely shiftable-Voucher i table. In these drawings Figure 1,

Figure 7 is a lateral view showing the differential members of the units key board, and

Figure 8 is a section on line VIII-VIII of Figure 2.

Referring to Figures 1 to 3, 1 denotes the table the edges 2 of which are bent upward to secure the voucher put thereon. The table is guided on transverse bars 7, 8 mounted on the frame of the kprinting mechanism, by means of roliers 3, 4, Figure 3, and check rollers 5, A large rectangular aperture -9, Figure 1, provided in the table 1 enables the .hammer (not shown) arranged opposite the printing drum 11, Figures 1 and 2, to effect the impression upon the voucher, which im-j pression takes place from the correspondingly set drum on the line 12, Figure 2.

The table 1 carries a rack 13, Figure 2, in

mesh with a dierential wheel 15 mountedon a carrier 14 and further in mesh with a rack 17 of abar 16 shiftably guided on the frame of the mechanism. The carrier 14 is rigidly connected by a fish-plate 20 to aber 18 likewise guided linthe frame of the meclil The bar 16 ,is set, in'a manner to be described hereinafter, in dependence upon the keysf19, Figures 1 and 4, provided for the units of the line number, whilst carrier 14 is set in dependence upon the keys 21, Figures 1 and 5,- provided for the tens of this number.

. After the termination of this setting motion two locking arms2-1, 25, Figure 2, are brought into mesh with locking teeth 28,' 29 of the bars 16, 18,l respectively. 25 are mounted on two pins 22, 23, iixed in connected to a pitman 27 iniiuenced from a cam disk 26. Due to this engagement the bars16, 18 are exactly set and locked in set 'position'.- In order to damp blows occurring i due to violent setting motion, the diierential rer A14. To this end carrier 14 is bifurcate'd,

The locking arms 24,'

` 90 A the frame of the mechanism, and are both Figures 1 and 8, and has oblong holes 32 wherein the journal 31 of wheel 15 rests and is normally held in contact with the righthand wall of the holes 32 by a spring 33.

The bar 16, Figures 2 and 4, carries a rack 34 on its right-hand end with which rack is in mesh a pinion 36 mounted on a shaft 35 fixed in the frame 6 of the printing mechanism. This shaft further carries a pinion 37, Figure 4, in mesh with a shiftably mounted rack bar 38, Figures 1, 2, and 4. The latter is in positive connection with a pinion 43 through the intermediary of a pinion 39,

Figure 4, a tubular shaft 41 mounted in the frame, and a pinion 42, the pinion 43 being fixed on a differential shaft 44 arranged below the units key row 19` Shaft 44 carries a series of lugs 45, Figures 6 and 7, that are distributed thereon along a helical line and adapted to co-operate with the feet of the individual keys 19. Therefore, when after depression of a key 19, shaft 44 is rotated so far that the lug 45 allotted to the depressed key 19 comes into contact with the latter, this rotation amounts to that number of angular units which corresponds to this key. Consequently also table lis shifted the same number of units through the intermediary of differential wheel 15, bar 16 and members 36, 35, 37, 38, 39, 41, 42, 43.

The described contact between the lugs 45 and the respective keys 19 is effected by an auxiliary differential member 46 mounted on shaft 44, Figures 6 and This member is formed by a sleeve which is cut away along a` helical line and has stepped engaging faces 47. Member 46 is positively connected to a rack 53, Figures 2 and 4, by pinions 48, 49, Figure 4, a sleeve 51, and a pinion 52.

shaft 54, Figures 1 and 2, has rigidly mounted on it swing arms the free `ends of which are bifurcated so as to form a slot 56 in which a block 57 is shiftable. This block carries a journal having mounted on it a differential wheel 59 permanently in mesh with the racks 38 and 53.

After one of the keys 19 has been depressed, a swing motion toward'the left, Figure 2, is imparted to the arms 55, the journal 58 assuming the position58 and a total motion of ten units being transmitted to the racks 38, 53. Whilst the lugs 45., Figure 7, of the main differential member 44 in the position of rest are an angular distance away from the respective key feet which corresponds to the numeral of the key, the angular distance of the faces 47 of the auxiliary diii'erential member 46 from the key feet in this position corresponds to the complementary value of the numeral of the key. The total motion of ten units imparted to the racks 53, 38 thus is so distributed on them that the main differential member 44 and therewith the bar 16 and table 1 move by the value corresponding tothe de pressed key 19, whilst the auxiliary differential member 46 moves by the value which is complementary to the former. The motion of the two differential members takes place in opposite direction, Figure 6. At the end of the driving motion of the swing arms 55 the lugs 45, 47 abut from both sides on the foot of the de ressed key. Any lag of diff ferential member 44, as it may occur when actuated by an external force, in particular if resistances arise on the table e. g. by the voucher crimping, is thus impossible.

The keys 19 are equipped with lateral pins 61 by which they co-operatev with a locking bar 62 that in known manner locks the keys in depressed position. The locking bar 61 has rigid on its forward end an arm 63 which as long as no key is depressed projects into the path of a stop 64 fast on shaft 44 and stops the latter in zero position. By depressing a key the locking bar 62 is shifted to the left, Figure 4. The left-hand side walls 65 of its locking hooks are so arranged that bar 62 cannot be retired by its spring 66 to its extreme right hand position, if a key 19 is maintained in depressed position. In this position of bar 62 arm 63 is out of the path of stop 64, so that shaft 44 is free for the differential motion.

In a similar manner a main differential member formed by a shaft 67 and an auxiliary dilierential member formed by a mutilated sleeve 68 are provided yfor the row of tens keys 21, Figure 5. Shaft 67 is positively connected by pinions 69, 70, 71 to bar 18 connected to the differential wheel carrier 14, and is connected by a. tubular shaft 72 fast on pinion 71, and by a pinion 73 to a rack 74 which corresponds to rack 38 of the units place. The auxiliary differential member 68 is in positive connection with a rack 79 through pinions 75, 76, a tubular 77, and a pinion 78; rack 79 corresponding to rack 53 of the units place. A differential wheel 81, Figure 1, likewise mounted on journal 58is in mesh with the racks 74 and 79 and imparts to them a total shifting motion of ten units, upon arms 55 rocking, whereby the stepped lugs of the two differential members 67, 68 are moved from both sides onto the foot of the depressed key. In the same manner as in the units place the ke locking bar 82 is fitted with an arm 63 whic locks the main differential member 67 in zero position as long as no key 21 is depressed.

The tens key board comprises three keys 10, 20, and 30, Figures 1 and 5; the lu s, cooperatin with them, of the main di erenti'al mem er 67 are so arranged and the ratio of transmission from the latter to the differential wheel carrier 14, Figure 2, is so determined that the latter is moved 5, 10, or 15 units by depressing, respectively, key 10, 20, or 30. By the differential wheel 15 double the amount of the motion of carrier 14 is transmitted to the table 1, so that the latter lll) ' at most two places. Thereis no hindrance,

adjusts itself to the line 10, 20, or 30, .upon respectively, key 10, 20, or 30 being depressed.

Therefore,by depressing the respective unitsl and tens keys the table 1 can be adjusted to every one of the lines 1 to 39.

The described line adjusting mechanism is intended for a number of lines comprising however, to design the mechanism for a. number comprising more than two places. To this end only the differential gear 13 to 16, Figure 2, had to be modified accordingly. For a number of three places, this could be made e. g. by not rigidly connecting rack 13 to table 1, but by means of a diiierential wheel the carrier of which is set by the hundreds key row to be provided for in addition;

The key rows for the line adjusting mechanism are annexed to the account number key field, whereby much space is saved and the manipulation is simplified in comparison with mechanisms having transversely extending key rows. As to be seen -from Figure 1, the account number keys 83 are arranged on the left and the date keys 84on the right bea printing mechanism comprising a table,`
